ROCK-GRUSHER.

Specification of Letters Patent.

Patented be... 10, 1907.

Application filed June 11. 1906. Serial No. 321097- scription, reference being had to the accompanying drawings, which form a part of this specification.

The object of my invention is to provide an improved jaw crusher for crushing rocks, ore, stones, etc., which shall be simple and comparatively inexpensive in construction but at the same time of sufficient strength and durability to be efficient for all except the heaviest work.

The invention consists of a new and improved detachable connection between the main cam shaft or driving shaft and the moving jaw, and also of new and improved means for guiding the moving jaw or jaws on the frame and taking the wear thereof.

The invention is shown embodied in a machine of the multiple jaw type, as set forth broadly in an application filed of even date herewith, Serial No. 321,096. Although it will be understood that my improvements are equally applicable to a machine of the single jaw type.

In the drawings: Figure 1 is a plan view partly in section, of the crusher; Fig. 2 is a longitudinal vertical section; Fig. 3 is a rear end view, partly in section; Fig. 4 is an enlarged detailed sectional view of the guide plate and wearing plate and their connections with the frame and moving jaw respectively Fig. 5 is an elevation of the same from the inside.

The frame is a solid cast structure comprising the side plates 10 and the end plates 11. The frame has foot flanges 12 for boling to the bed timbers 13. Also cast on the side 'plates 10 are the journal boxes 14, in which the main cam shaft or driving shaft 15 is held. 16 are fly wheels secured to the main shaft. These fiy wheels serve as belt wheels for driving the machine, and also as traveling wheels in transporting the machine from place to place when the supporting timbers are moved.

17 are cams (shown as two in number) on the main shaft. The two cams are eccentrics and are so secured to the main shaft that their longest radii extend in diametrically opposite directions.

' strap surrounding each eccentric. The two halves of a strap are provided with lugs 20, through which extend bolts 21 by means of which the strap is held on the eccentric.

The moving jaws 22 are pendulous from a shaft 23 extending through and between the side plates 10 and secured in boxes 24 cast on the outer faces of the side plates. The rear face of each jaw is provided with a recess in which is secured the wearing plate 25, and

tion in its recess, the wearing plate being secured into place by inserting one of the lower corners of the same between the jaw and overhanging lip and forcing the plate in lat erally. The recess andwearing plate is provided with a concavity, and into the concavity in the plate extends the rounded end of a toggle 27 which is cast on the corresponding strap section 19.

Rods 28 are pivoted to lugs 29 on the moving jaws 22 and extend rearwardly through the rear end plate and spring seats 30 cast therein. In these seats are the springs 31 surrounding the rods 28 and working against collars 32 secured to the rods. The springs 31 assist in drawing the moving jaws backwardly and holding the toggles in their seats.

The removable and reversible face-hardened dies 33 are set into recesses in the faces of the moving jaws. To hold the dies in place, wedge shaped keybolts 34 extend through orifices in the jaws just above the upper ends of the dies and into the space between the upper end of the dies and theupper faces of the die recesses. By tightening the nuts on the key-bolts, the dies 33 are forced downwardly against their dovetailed seats. jaw or die 35 rests against the inner face of the end plate and upon the die rest 36 which extends between the side plates and is secured thereto. On the outside face of the said end plate is the washer 37. The washer, end plate and die have alining orifices, the lower wall of the orifice in the die tapering downwardly and forwardly.

38 are the key-bolts, each of which extends through the alining orifices in the end late and Washer, and has a Wedge-shaped head extending into the tapered orifice in the 18 and 19 are the two halves of a sectional I The removable and reversible fixed lips 26 cast on the aw hold the plate in posidie. By tightening the nuts on the keybolts, the die is forced against the die rest 36.

Extending into an orifice in each side plate (see more particularly Fig. 4) is a guideblock comprising a cylindrical body or shank portion 39, an end guide-plate 40 closing its inner end, and an outside flange 41.

42 is a washer between the flange of the guide-block and the outer face of the side plate and 43 are bolts by means of which the guid e-block is secured to the side plate. Inset in the adjacent face of the adjacent moving jaw is the guide'plate 44. The guideplate 40 and guide plate 44 are just in contact, and thus provision is made for guiding the aw in its movement and taking the wear thereof. As the faces of the guide plate 40 and guide plate 44 wear away, the washer 42 may be removed or a thinner washer substituted, and the bolts tightened.

45 are the rectangular cheek plates or liners, reversible and interchangeable side for side, secured to the inner faces of the side plates opposite the crushing faces of the aws.

While I have described. a machine comprising two moving jaws, any number of jaws may be employed, but if three are employed, then three eccentrics are provided whose longest radii should be arranged at angles of 120 degrees with reference to each other. In a four jaw machine the four operating cams should be arranged so that their longest radii are 90 degrees apart.

When the main shaft is rotated, the eccentrics act successively to move forwardly the straps, which in turn, through the toggles, move the movable jaws toward the fixed jaw, crushing the material held therein.

The size of the crushed product is determined by the width of the space between the lower ends of the two jaws. By means of the sectional strap construction the section 19 may be removed and another section, having a longer or shorter toggle, may be substituted, whereby the size of the crushed product may be varied.

Having now fully described my invention, what I claim and desire to protect by Letters Patent is:

1. In a rock crusher, the combination with the moving jaw and a shaft from which the same is pendulous, and the fixed jaw, of the main shaft, a cam thereon, a strap on the cam having a removable section and a toggle on the removable section of the strap, said toggle having a rounded head, there being a cup-shaped recess in the moving jaw, and a wearing plate of substantially uniform thickness having its central part dished in to con form on one side to said recess and on the other side to the rounded head of the toggle.

2. In a rock crusher, the combination with the side plates of the frame, of a jaw suspended from the frame and movable between the side plates, a guide-plate secured to the side plate, and a guide-plate secured to the side of the jaw opposite and adjacent to the guide plate, and means to adjust the first guide plate inwardly toward the second to maintain them in proper relation notwithstanding wear.

3. In a rock crusher, the combination with the side plates of the frame, of a jaw suspended from the frame and movable between the side plates, an inwardly adjustable guideplate secured to the side plate, a guide plate, secured to the side of the jaw at its lower end, opposite and adjacent to the first guide plate, and a cheek plate secured to the inner face of the side plate substantially opposite the crushing face of the j aw.

4. In a rock crusher, the combination with the side plates of the frame, of a jaw suspended from the frame and movable between the side plates, a guide-block secured to the side plate and comprising a body'or shank portion extending through an orifice in the side plate and a guideplate at its inner end, and a guide-plate secured to the side of the jaw opposite and adjacent to the first guideplate.'

5. In a rock crusher, the combination with the side plates of the frame, of a jaw suspended from the frame and movable between the side plates, a guide-block comprising a body or shank portion extending through an orifice in the side plate, an outside flange and an inner guide plate, and bolts by which the flange is secured to the side plate.

In testimony of which invention, I have hereunto set my hand, at Philadelphia, on this 5th day of June, 1906.
